Record your microphone audio input and get an audio/mp3 or audio/wav file in the end.
Written in TypeScript
npm install mic-recorder- Watch for changes:
npm run watch- Regular build:
npm run buildconst MicRecorder = require('mic-recorder').default;
// or
// import MicRecorder from 'mic-recorder';
// New instance
const recorder = new MicRecorder({
bitRate: 128,
encoder: 'mp3', // default is mp3, can be wav as well
sampleRate: 44100, // default is 44100, it can also be set to 16000 and 8000.
});
// Start recording. Browser will request permission to use your microphone.
recorder.start().then(() => {
// something else
}).catch((e) => {
console.error(e);
});
// Once you are done singing your best song, stop and get the mp3.
recorder
.stop()
.getAudio()
.then(([buffer, blob]) => {
// do what ever you want with buffer and blob
// Example: Create a mp3 file and play
const file = new File(buffer, 'me-at-thevoice.mp3', {
type: blob.type,
lastModified: Date.now()
});
const player = new Audio(URL.createObjectURL(file));
player.play();
}).catch((e) => {
alert('We could not retrieve your message');
console.log(e);
});This library uses lamejs as a direct dependency. We build our releases with lamejs built-in, so you don't need to add another dependency.
Thanks to @zhuker for writing the lamejs library.
